But when i got on it hard on a launch it was the same.
Leading evidence: 'same' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'same' (1 discussions; 1 report identifying it and 0 suggest it). No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Got my 04 C4S in june. Had a new clutch put in as part of the purchase. Paperwork shows factory parts were used. The place that performed the work is reputable and post on this site. For the first 2 months i babied the car to make sure the clutch was happy. A few times i have been very aggressive. I have seen a few times where the clutch will slip going into 2nd. Again only while being aggresive. Are the factory clutches known to be crap?
I just noticed this same thing on my 99 only in second gear and only if I'm getting on it aggressively as well. My clutch is not new but your post has me thinking now, maybe not the clutch? its quite stout in first, I can drop the clutch and it grabs and roast the tires easily. I'v only done that a couple times (this past weekend) but I would have thought I would have noticed some slipping in 1st gear with a clutch dump and it didn't.
engine rpms going sky high but the car isnt going much faster. Clutch smell after the fact. I saw another post said he can roast the tires on a hard launch. I realize mine is all wheel drive so that wont happen. But when i got on it hard on a launch it was the same. Slipping clutch and stunk like hell. Only allowed it to happen for a second or 2.
normal driving and its fine. If im already in gear and i stand on it, everything is ok. It only occurs upon gear change.
very disapointing. I feel like if i take it back it will be a song and dance about another part issue or the flywheel is the problem. Either way im sure it will be more money needed.
I�ve noticed that if you don�t rev match these cars - engage the clutch at the right RPM - the clutch will slip. Are you matching the revs and then putting the hammer down?
I drive my car like this:
1) Engage clutch and gear and wait for complete lock
2.) Put the hammer down
3.) Lift, shift, rev match, clutch back out
4.) Put the hammer down again
Some people combine 1 and 2 or 3 and 4 in the same step. It�s technically faster, but technically the wrong way to drive a street car, and I think the wrong way to drive a Porsche.
I researched this before I saw what a 996 clutch looked like. Read many times how they last 45k-50K miles. I thought that was extremely low. After I saw the clutch disk, it made sense. There is not much surface area on the clutch disk!
I pulled the OEM clutch off my 2004 911 with 35K miles. The clutch disk looks so bad, I would not even consider re-using it.
We've had customers make 450+ HP and not had a stock clutch slip. The only times we've heard of issues is when an aftermarket (non-sachs) clutch is used.
